SDA and SCL pin waveforms.
These waveforms are the SDA and SCL pins waveforms they're used to show what bit is coming in at what time. The microcontroller communicates with the PCA9685 chip by addressing specific register locations using the I2C in the PCA9865.
Audio sensor waveforms
This wavefrom is the audio sensors waveforms. The OUT will output high level when the intensity of the sound from the outside environment is more than set threshold of the potentiometer the OUT will output low level.
